VPN Gateways
Some of the biggest challenges
facing hardware designers of VPN
equipment include designing
efficient encryption/decryption
technologies. These technologies
must provide increased security and
privacy, as well as sender/target
authentication, identification and
tracking. Current solutions increase
security and privacy, but require
the trade

overhead. At low bandwidth speeds,
transmitting the payload plus
authentication additions slows down
data transmission times to a snail's
pace. As shown in Figure 3, the
PowerDrive HT7520 connects the
CPU to a security processor over a
6.4MB/s point-to-point interconnect
bus. VPN applications benefit
immediately through decreased
transmission times of secure,
encrypted data.

By adding the PowerDrive device, there is a
48X bandwidth increase over a standard 33
MHz PCI connection. High-speed network
connectivity is also enhanced via the
availability of two 133 MHz PCI-X bridges.
The PowerDrive HT7520 is a high-speed,
scalable HyperTransport solution that
alleviates VPN interconnect bottlenecks and
provides expandability for tomorrow's
functionality.
